The Toyota 6FG 6FD 10-30 Forklift Repair Manual 1994 opens with a complete section index running from General through to Appendix, so the whole shop floor workflow is mapped before you turn a wrench. It is written for the 6FG and 6FD 10-30 series as they stood in January 1994, and Toyota notes that later design or specification changes are communicated separately through Parts & Service News – which is exactly why a dated factory-issue document like this is worth keeping in the workshop.

Read as a whole, the Toyota 6FG 6FD 10-30 Forklift Repair Manual 1994 is a complete teardown-and-rebuild reference rather than a quick-glance guide. Each section moves from the general arrangement drawing through the component figures, then into removal, disassembly, inspection, reassembly and the point operations that carry the critical measurements – press strokes, match marks, shim thicknesses, grease points and the order in which parts must come apart so nothing gets damaged on the way out.

Model and Engine Coverage

The manual covers the 1 ton series (6FG10, 6FG14, 6FG15, 6FG18 / 6FD10, 6FD14, 6FD15, 6FD18), the 2 ton series (6FG20, 6FG23, 6FG25 / 6FD20, 6FD23, 6FD25) and the 3 ton series (6FG28, 6FG30 / 6FD28, 6FD30), in both clutch and torque converter drive configurations. A dedicated model table also lists the South Africa variants (6FGA15, 6FDA15, 6FGA18, 6FDA18, 6FGA20, 6FDA20, 6FGA25, 6FDA25, 6FGA30, 6FDA30) and the Indonesia variants (6FDN20, 6FDN25, 6FDN30).

Engine coverage spans the 5K and 4Y gasoline units, the 1DZ diesel and the 2Z diesel. Where a procedure sits with the engine rather than the chassis, the foreword points you to the matching Toyota engine repair manual – 5K (No. CE617), 4Y (No. CE602), 1DZ (No. CE618) and 2Z (No. CE625) – so the Toyota 6FG 6FD 10-30 forklift repair manual works alongside those titles rather than replacing them.

Torque Values, Capacities and Service Data

Hard numbers are spread through the document rather than bundled into one table. The General section carries a full standard bolt and nut tightening torque table broken down by bolt class (4T, 5T, 6T, 7T) and diameter, plus a high pressure hose fitting torque chart indexed by thread size and hose bore. Component weights are listed per model, so you know what you are lifting before the hoist goes up.

Lubricant and fluid data cover engine oil, transmission and torque converter oil, differential oil, hydraulic oil, fuel tank capacity, brake and clutch fluid, coolant and chassis grease, with coolant volume tables for every engine and drive combination and a separate hydraulic oil volume table for the 1, 2 and 3 ton series. A lubrication chart splits inspection and replacement intervals into daily, weekly, monthly, six-monthly and annual blocks, and the periodic replacement table tells you when oil filters, hydraulic return filters, brake fluid, hoses and chains are due.

Diagnostics and Testing Procedures

The torque converter section is where the diagnostic work really lives. A fault-status troubleshooting table pairs symptoms – no movement, insufficient gradeability, delayed engagement, inching jerk, overheat, abnormal noise, oil leak – with an inspection method and the likely cause, then points to the corrective action. Oil pressure measurement covers main pressure, clutch operating pressure and torque converter outlet pressure, and a stall test procedure with stall speed figures for the 5K, 4Y, 1DZ and 2Z engines lets you separate a converter fault from a clutch fault.

On the hydraulic side, the material handling section gives you the natural drop test, the natural forward tilt test and the oil leak test with the acceptable leak volumes at the lift port and the combined lift and tilt port. The steering section adds a relief pressure measurement procedure, and the oil control valve section walks through relief pressure adjustment for both the lift and tilt sides with the correct cap nut and lock nut sequence.

Exploded Views and Component Figures

Component figures throughout the Toyota 6FG 6FD 10-30 forklift repair manual are taken from the parts catalog for the vehicle model, with the FIG number printed at the shoulder of each drawing. That makes cross-referencing between the repair manual and the parts catalog straightforward when a part has to be identified or ordered. Major assemblies – the transmission, control valve body, clutch cover, torque converter and oil pump, differential carrier, front and rear axle hubs, steering gear box, power cylinder, brake assemblies, masts, lift and tilt cylinders – are all illustrated as exploded views with numbered callouts and the tightening torque called out where it applies.

Who This Manual Suits

This is written for the person who has to put a 6FG or 6FD 10-30 forklift back into service, not just read about it. Workshop technicians will use it for clutch and torque converter overhauls, transmission rebuilds with shim and thrust clearance adjustment, differential ring gear backlash and tooth contact work, brake shoe and wheel cylinder service, mast roller and strip shimming, and hydraulic relief pressure setting. Fleet maintenance staff will lean on the periodic maintenance inspection method, the lubrication chart and the replacement intervals to build a service schedule. Owners of a single machine get the same procedures and measurements the shop uses.

The value here is in the specifics. Shim thickness options, wear limits, rivet sinking depth, bushing inside diameter limits, backlash ranges, starting force figures, spring free lengths and parallelism limits are all listed – the numbers you need to decide whether a part goes back in or gets replaced, and the assembly sequence that keeps a precision control valve or a clutch drum from being damaged during reassembly.
